您好、TI 团队、
目前、我正在将 BQ79656-Q1 IC 用于汽车 BMS 应用。 我们在 BAT 引脚提供56伏电压。 通过使用 ping 命令、可得到 LDOIN=6.0V、AVDD=5V、REFHP=5V、TSREF=0V、NEG5V=-4.7V、CVDD=5V、DVDD=1.8V。 在这个阶段,一切都很好。
我将1个 BQ79656-Q1 BMS IC 与 R5F10BGG 主机控制器配合使用。 我正在使用波特率为1Mbps 的 UART 通信。 将 BQ79616-Q1的"TMS570"参考代码移植到 R5F10BGG 微控制器中。
现在、问题是我无法读取电池电压。 我正在发送数据"0xC0、0x05、0x68、0x1F、0x42、0x2D"以读取电芯电压。 我 还会检查从主机控制器传输到 CRO 上的 BQ79656-Q1以及 USBTOTTL 转换器的数据。 此外、还会在 BQ BMS IC 的 RX 引脚接收数据。
请帮助我解决此问题。
在此代码中、我们将使用自动寻址功能。 还有 一点我想知道、我们如何知道我们的器件地址(BQ79656-Q1)？
在传输的字符串 "0xC0、0x05、0x68、0x1F、0x42、0x2D"中、我认为地址是5。
我也在分享代码的某些部分……
此致、谢谢。
迪帕克
